The ADA4522-1ARMZ is a 55V, EMI enhanced, zero drift, ultralow noise, rail-to-rail output operational amplifier in 8 pin MSOP package. It is a single channel, zero drift op amp with low noise, low power, ground sensing inputs and rail-to-rail output optimized for total accuracy over time, temperature and voltage conditions. The wide operating voltage and temperature ranges as well as the high open-loop gain and very low DC and AC errors makes the device well suited for amplifying very small input signals and for accurately reproducing larger signals in a wide variety of applications. The performance is specified at 55V power supply voltage. This device operates over the range of 4.5V to 55V and is excellent for applications using single-ended supplies of 5V, 10V, 12V and 30V. Typical applications include LCR meter/megohmmeter front-end amplifiers, load cell and bridge transducers, magnetic force balance scale, high precision shunt current sensing and thermocouple/RTD sensors.
